摘要： Described herein are systems, methods, media, and devices for generating a satellite program for contacting satellites. In some embodiments, data including one or more targets for accessing a satellite constellation is obtained. Based on the data, a set of representations may be generated and candidate satellite constellation access programs may be determined based on the set of representations. For each program, a first score may be computed for each target to obtain a first set of scores, and a second score may be computed for each first score of the first set of scores to obtain a second set of scores. A satellite constellation access program may be selected from the candidate satellite access programs based on the second set of second scores.

摘要： Systems and methods of the present disclosure may use a satellite operations center (SOC) to access an activity queue of satellite activity tasks in an activity buffer, each satellite activity task being associated with at least one satellite in a fleet. The SOC may determine mission critical variables associated with each satellite activity task based on space environment context data, satellite telemetry data, the position of each satellite, and the trajectory of each satellite. The SOC may determine, for each satellite activity task, using at least one statistical model, a prioritization tier based on the mission critical variables of each satellite activity task, and determine a satellite activity order defining an order of the satellite activity tasks based on the prioritization tier of each satellite activity task. The SOC may modify the activity buffer to order the satellite activity tasks in the activity queue according to the satellite activity order.

摘要： The present invention relates to a method performed by a terminal operating in a stand-alone non-public network (SNPN) connection mode in a communication system. The method comprises the steps of: receiving, from a base station, a radio resource control (RRC) release message including reservation configuration information; entering an RRC deactivation state on the basis of the RRC release message; performing a cell reselection procedure; and triggering an RNA update procedure when a cell selected according to the reselection procedure is not included in cell information included in notification area information.

摘要： A method performed by a first network node serving a first terminal when handling a call between the first terminal and a second terminal is provided. The first network node determines that the call is associated with longer than expected delays between the first and second terminals. The network node provides a Long Delay Indication to at least one of said first and second terminals to indicate said longer than expected delays in the call.

摘要： An operation method of a satellite in a non-terrestrial network may comprise: determining a frequency resource allocation order for allocating frequency resources to beams in consideration of a frequency band of a terrestrial system and degrees of interference to the terrestrial system; configuring a minimum performance condition for maintaining a service of the non-terrestrial network, the minimum performance condition being applied to each of the beams; configuring an operating condition of a multi-agent deep reinforcement learning for each beam controller of the satellite; and controlling the each beam controller to sequentially allocate the frequency resources to a managed beam according to the frequency resource allocation order while considering the minimum performance condition.

摘要： A method and apparatus may include identifying, by a network entity, at least one link change corresponding with at least one round trip time (RTT) change, and transmitting, by the network entity, at least one first indication of the at least one link change to at least one serving network entity. The at least one first indication is configured to cause the at least one serving network entity to transmit at least one second indication of the at least one RTT change to at least one user equipment.

摘要： Inventive technology is directed to a control method for a terminal device in a non-terrestrial cellular data communication network. In an embodiment, the network includes at least one airborne or spaceborne base station moving along a flight trajectory for connecting the terminal device to the network. The method includes steps of: providing flight trajectory data for the base station in a memory element of the terminal device; providing terminal location data in a memory element of the terminal device; using a data processing unit, determining at least one time slot during which a wireless communication channel between the terminal device and the base station is estimated to be available, based on the flight trajectory data and on the terminal location data. The method also includes scheduling a data reception or transmission between the terminal device and the base station during the determined time slot.

摘要： A satellite receiver for wireless signals having carrier frequencies in the V or the W band of frequencies is described. The satellite receiver may receive the wireless signals at high elevation angles, such as greater than 62°. This high elevation angle may reduce losses, which may allow the satellite receiver to communicate at a data rate of at least 50 Mbps. In order to accommodate these system requirements, the one or more satellites that provide the wireless signals may have eccentric geosynchronous or near-geosynchronous orbits that are inclined relative to an equatorial plane of the Earth, such as an eccentricity between 0.12 and 0.3. Moreover, the one or more satellites may have ground tracks substantially along one or more continents, and may be in view of dense population regions in the one or more continents with a higher frequency than low-density population regions in the one or more continents.

摘要： A system includes antennas to receive satellite signals, modems for managing data received from the antennas, and a switching unit for managing the allocation and the transmission of the data from the various antennas to the various modems, the data from any one of the antennas being able to be allocated and transmitted to any one of the modems, the system thus being able to adapt the allocation of the data such that each modem is able to continue to receive data relating to signals transmitted by one and the same satellite upon a change of position of the antennas, thereby making it possible to maintain communication to one or more given satellite communication services.

摘要： A system is provided for reducing latency data collection from space-based sensor satellites. A mobile vehicle platform, configured to travel around the Earth, includes a sensor module and a relay satellite terminal. The sensor module monitors certain conditions, circumstances, environments and/or situations occurring on or around, or associated with, the Earth, and generates sensor data resulting from the monitoring. The relay satellite terminal executes data communications with a first of a plurality of satellites while the mobile vehicle platform is in a first area within a communications range of the first satellite, and, upon moving to a second area within a communications range of a second of the plurality of satellites, the relay satellite terminal switches the data communications to the second satellite. The data communications relay the sensor data, via the satellites, to a central processing facility for aggregation, processing, analysis and/or dissemination of the data.
